BRUSSELS (AFP) - European Commission chief Jose Manuel Barroso on Friday congratulated US President Barack Obama on his Nobel peace award, saying it would encourage people hoping to build a safer world.

"The award of the prize to President Obama, leader of the most significant military power in the world, at the beginning of his mandate, is a reflection of the hopes he has raised globally with his vision of a world without nuclear weapons," Barroso said in a statement.

"This award is an encouragement for engagement by all those who can contribute to bring about a safer world.

"It is also a recognition of the expectations created everywhere by President Obama's determination to work closely with the United States' partners to shape global responses to the global challenges we face today," he said.

Obama sensationally won the Nobel Peace Prize on Friday less than a year after he took office with the jury hailing his "extraordinary" diplomatic efforts on the international stage.
